UFOs have always fascinated the public and sightings and reports are frequent. The Advanced Aerospace Threat Identification Program (AATIP) is the Pentagon's mysterious UFO program that was previously run by Luis Elizondo. Three videos of encounters were released to the public in 2017. Elizondo left his position after expressing concerns of national security and potential vulnerability. He now exposes a series of encounters and journeys on new investigations that urge the public to ask questions.
